EDWARD Woollard, 18, a former A-level at Brockenhurst College, has been jailed for two years and eight months in a young offenders’ institution for lobbing a fire extinguisher from a seventh floor rooftop onto the crowd below on November 10 2010.

The judge told him:

“The right of peaceful protest is a precious one. Those who abuse it and use the occasion to indulge in serious violence must expect a lengthy sentence of immediate custody…. It is perhaps ironic that the weapon which you threw down from the top of this very high building and which was calculated to inflame passions was a fire extinguisher.”
